Currently there is no easy way to swap the red and green LEDs in this model except for swapping the head, which is little difference than replacing the whole light.
We brought this inquiry to the manufacturer before. The engineers tell us that this model is designed to be adapted to one color LED only for the reasons below
1) Red and Green LED actually has different voltage requirement for the circuit. To bright out the best performance, the driver has to be designed exclusively for different LEDs.
2) The LED has to be placed precisely at the center of the reflector to achieve the maximum throw range. This is almost impossible when a user swaps it.
3) The light head is sealed and the LED is embedded to achieve the maximum impact and water resistance.
This model is, without a doubt, the best green/red LED hunting light on the market. However, to reach this performance, the factory makes the compromise by not allowing users to swap different LEDs.
We understand that many people love to have options of different color LEDs. We are talking with the manufacturer to supply us LED head with relative low cost so we can either sell them as a part, or bundle it with the current model. We will keep you updated on the progress.
